Product Description

The Flowmaster Sound is the true tone of American muscle and performance. Available in a wide range of domestic and import applications for automobiles and trucks. Flowmaster mufflers produce more power than OEM and competitive aftermarket products.

This Force II exhaust system is not as loud as the American Thunder Exhaust System with less interior resonance. The Force II exhaust system has been designed with the latest exhaust technology available. Through this technology, you will experience improvements in acceleration, passing power, and fuel mileage. The key to these performance improvements is through the use of mandrel-bent tubing that allows for superior exhaust gas flow. Aluminized steel tubing has been used for its corrosion resistant quality so your system will last. The Force II system comes with a three chamber muffler(s) that will give you plenty of Flowmaster sound under hard acceleration but low sound levels while cruising. Kits include all hangers, clamps, and mounting hardware for an easy installation.

About Flowmaster

History and information about Flowmaster and their products.

The performance exhaust is an important part of your performance car. Flowmaster is one of the oldest and most respected and recognized names in aftermarket performance exhausts and one of the reasons LMPerformance carries Flowmaster American Thunder, and Flowmaster 40 Series Exhaust systems. For over thirty years Flowmaster has been one of the leaders in the design of specialty aftermarket exhaust parts. Flowmaster American Thunder & Flowmaster 40 series were first established to design and manufacture exhausts for racing in California. Flowmaster now produces performance exhaust systems, mufflers, and other products for a wide range of cars (including Mustangs, Camaros, Challengers, Corvettes, Chargers), trucks, SUV's, motorhomes and ATV'S. They create a line of high-performance "chambered" mufflers that is well known in the industry.

Flowmaster offers eleven diffferent series of mufflers that give top notch performance and great sound levels and tones. Flowmaster is especially noted for their Flowmaster 40 series muffler, with its original Flowmaster American Thunder sound and tone. If you're in the market for a Flowmaster 17106 Ford Mustang exhaust system- look no further!

By: srlewis76Ownership: 1 day - 1 weekI have the 1lt (base vette non npp exhaust). Installed this part yesterday evening with a friend. There is a video on youtube that was for another manufacturers larger system that helped with removal of the bumper and factory exhaust. On the way to work got a check engine light. Flowmaster is aware of the issue and is going to have me speak with R&D tomorrow!

By: HeaphchopOwnership: 1 day - 1 weekI watched countless YouTube vids of axle backs for my car. Let me say they're essentially useless! Based on the videos I had my heart set on a ford racing or borla touring exhaust. They seemed to have the deep sound I was looking for without being obnoxiously loud. I was avoiding the flowmaster setup based on a few videos that made it sound too high-end and not rumbly. I was set to spend 700 on the borlas but stumbled on a vid of the flowmasters that sounded good. So I decided to risk it to save some dough. I'm not disappointed. I put them on in under an hour. The fit is stellar. So easy to line up in the valence, looks great! If you're looking for a crazy loud system this is NOT for you. It's not much louder than stock, but has a much beefier sound. There's no drone in the cabin unless you really are looking for it. At cruising speeds with the radio on you can't hear the exhaust. Dip your toes into the gas tank and it roars pretty good, but again nothing obnoxious. I think it's perfect for a daily driver.

By: tjOwnership: 1 day - 1 weekHad the American thunder cat back installed by dealer. Sounds ok from the outside. Has a terrible load low pitch drone the feels like it vibrating the inside of the car. the sound is most noticable as the rpm reach the point where the car up shifts. The noise is very annoying. I will be making an appointment to replace the original.

By: Julian2411Ownership: 1 day - 1 weekCar sounds more than amazing! I would recommend this product to anybody that wants to get there money''s worth, but more importantly make there car sound amazing and a head turner.

By: MikeOwnership: 1 week - 1 monthFirst of all, shipping was VERY fast - thanks!
Install was pretty straightforward. Took a little less than 2 hours. The clamps supplied are top-notch.
The sound of this exhaust is great! Very, very deep sound, especially under 2000 RPM. I find it has the most interior resonance from 1500-1700 RPM, but I rarely cruise in that range - and I love the sound anyway. The often-talked-about drone at a 2000 RPM cruise is almost non-existant on my car (3.73 gears, manual trans). At highway cruising speeds, they are not loud, but you can tell they are there if your radio is off. Under heavy throttle, they are fairly loud, but not obnoxious.
I highly recommend this system to people who like hearing their exhaust at part-throttle acceleration as well as WOT. If you like it silent inside with the windows up, you might want to look into quieter alternatives.

By: MikenhollandOwnership: 1 day - 1 weekI did alot of research on doing such an upgrade, I found this system to be the cheapest in cost compared to other sites, and on Ebay. There is even a video on YOUTUBE that shows the step by step process to doing the removal of the old system and install of the new. Just do a search for Dodge Charger Flow master and I'm sure you will find it. I watched it I don't know how many times looking to see if they were leaving anything out so once I got the system delivered my only problem was cutting the pipe. I had no way of lifting it on a hoist or jacking it up more than 2 feet but in all honesty, this system can be installed in about 10 minuts if have have all the tools readly availabe and you dont have to stop to get out from under the car. I bought ramps at autozone drove up the front end then jacked up the rear end and used jack stands to support everything I was small enough to fit under and make the cut and everything went as smooth as the video I was really excited to how easy everything went once the cut was made and everything fell right out. Do soak all the rubber mounts and loosen them up prior to remval, you won't have to fight as much, keep the very rear one in place. The exhaust does have a rumble at idle and did turn heads when I got on it, however this is not a loud system and that works perfect for me. I really just wanted dual exhaust with just a little bit of noise. I am 100% happy. Also the exhaust clamps provided are the same oem style ones and do not look as cheap as the ones in the video.

Current Mods:I bought my 09 SXT in the summer of 08 It is the deep blue pearl color, it was as plain as could be considering it started out as a rental car so what I have done so far was tinted the windows all around to 35%, added black lower door/body graphics, side 1/4 panel graphics, and of course the hood graphics, installed a black OEM spoiler, black OEM front lower lip spoiler, black aftermarket "mesh" grille, painted the calipers blue, installed american racing black with machined lip rims, LED license light, trunk, and interior light bulb upgrades, HID fog and headlight bulb upgrade, cold air intake with blue hoses with mopar decals, black leather seats with blue stiching, the front have blue that run the center of the seats, and now the flowmaster exhaust system.

By: CAPOwnership: 1 month - 1 yearLooked around and found the Force II exhaust to be the best one for a driver not looking for the sound as much as better p/u and gas mileage. LM Performance by far had the best price. Came complete and all parts are wraped so no scratches, dings, needed nothing extra all parts included. Took it to Dennis my mechanic and in 1 hour we had it on and welded it also. Very nice looks and sound gets better in time. Very mild. I had gone to Utube to here it prior to buying. Very happy!!!

By: 2011 camOwnership: 1 day - 1 weekGreat system. Strapped it to the chassis dyno and it does everything flowmaster said. 5 more peak horse at the wheels and great bottom end gain. With the improved low end power I'm pulling 2.5 more mpg, IMPRESSIVE! *PLEASE NOTE* I installed this on a 2011 and the instructions say to cut 9 inches forward of the hanger. This is incorrect, I cut 6.5 inches forward.

By: RilesOwnership: 1 week - 1 monthInstallation wasnt too bad, took about 2.5 hours (most of the time spent trying to gently jack up the car and then lowering it back down. There were three bolts on the left muffler and two on the right. Sounds great

By: LTMOwnership: 1 week - 1 monthI recommend this product to anyone looking for more power and sound. I have it on my camaro and I love the sound of it. Everyone I talk to complements it on the great sound.

By: GunnerOwnership: 1 week - 1 monthThe quality of construction on this kit is excellent, actually much nicer than some more expensive competitors. If you are looking for a loud exhaust look elsewhere, this is a very mild sounding kit free from drone at any speed. The power increase is noticeable, definately a worthwhile kit for performance and daily driver friendly tone. Good job flowmaster!!!

By: DWBcons_SSOwnership: 1 week - 1 monthThis is just what Iwas looking for. I order the Flowmaster Hushpower kit on Sunday and they where hear on Wednesday. It only cost me $54 at a local Muffler Shop. The sound is just what I wanted. I want the deep sound and a little more HP. I am very happen with LMPerformance and Flowmaster

By: QuattroOwnership: 1 day - 1 weekThe item was shipped very quickly, with 36 hrs from order to delivery. The installation was a breeze at an area muffler shop, taking less than 20 minutes. The sound is throaty and deep; but not loud. Nice rumble...especially on downshift at low speed. They are a quality product; priced fairly, and offer quick installation and great sound!

By: DOwnership: 1 day - 1 weeki have to admit, not knowing a whole lot about exhaust systems i was a bit skeptical about buying anything over 200.00, but i came across this site and it was only 186.
all of the videos on youtube make the exhaust sound rather... ricey.
but let me tell you, in real life, they do not disappoint.
excellent buy, excellent upgrade.
nice deep throaty sound.

By: VumanOwnership: 1 month - 1 yearInstallation-best if you use a professional!!
If you have a lift- go for it, But other under the tree mechanics will have a had time with the clearance.
Awesome Sound with great power improvement!!
Price just right!!

Current Mods:Just had Midas installed these Cat-Back on my 2010 Camaro. They Sound Awesome!! Deep aggressive Tone!! Quiet enough inside!! A Must for the Money!!

By: Chris DOwnership: 1 day - 1 weekI actually bought these to replace the 17410's that I had installed a couple of years back. Overall I think they are made pretty well. The sound is a little deeper than the 17410's which is nice. They are not too loud but you can tell they are there. Yes there is some drone but same as the reviewer above me I expected that. I have always liked the Flowmaster sound and have never had any problems with their products. It's a good product for a great price. LMP shipped them out immediately. All that being said I have only had them on for a couple of days now but I am happy.

By: ChrisOwnership: 1 day - 1 weekThis is a good set of aftermarket mufflers. They sound good and are not too loud. There is a bit of drone from about 1700-2000 Rpm's. It does not bother me, I knew these Flowmasters would do that. I think they are very good and I am satisfied. They do give a very deep tone. I have gotten several compliments about the sound on take-off and idle. If I had it to do over, I would still buy them. Thanks LMPerformance for the best price I could find. You have a customer in me for years to come and I will recomend you to all of my fellow car enthuiasts.

By: MoparfanOwnership: 0 - 1 dayThis was a great product, quickly delivered. Easy to assemble with great blueprints and easy instructions. This is the cheapest and best sounding product that I have found for my 07 Ram 1500 with a HEMI.. Now it sound's like a Hemi is under the hood...

By: DaveOwnership: 1 day - 1 weekThis is on my 1995 T-bird 4.6L with 66K miles. This is an awesome sound and performance improvement, has an excellent tone while cruising and install was a breeze. Took about 1/2 hour to remove internal cat material but was worth it. A++++

By: Mustang SallyOwnership: 1 day - 1 weekThis exhaust system looks and sounds great. It purrs in idle and roars when goosed. The system is not overbearingly loud but can definitely be heard. The price on this system is great too. LMPerformance did it right and had it shipped very quickly. 5 Stars in my book.
